Xperia Z1 Compact Disassembly_2The Sony Xperia Z1 Compact is a marvel of engineering in that it packs most of the Xperia Z1’s innards including the powerful chipset and 20.7MP camera sensor in a smaller chassis. The main compromise is a 4.3-inch 720p display instead of a 5-inch 1080p display, although we doubt in real life use you’d be able to tell the difference in pixel density between the two handsets.

To give you an idea of Sony’s engineering prowess, Russian site DGL disassembled the Xperia Z1 Compact and included a teardown video to show how it was done. They confirm in their write-up that the back cover is indeed plastic, which can be removed with heat from a hair dryer. Click through to find some disassembly pictures and teardown video (in Russian).

Once the case is opened, you can see the 2300mAh battery and NFC-antenna.

In previous Sony flagship devices, you could access the electronics as soon as the back cover was removed. In the Xperia Z1 Compact, to access the electronics you need to remove both the battery and another plastic partition first .

This plastic partition is mounted on double-sided tape, ensuring a water tight construction. It is impossible to remove this part without damaging the tape, therefore be aware your phone will no longer be water resistant. Another issue when removing the motherboard is that all connectors are located underneath it. This means trying to reconnect it is very tricky.

The back side of the motherboard is almost bare, unsurprising given the tight fit.

The front part is arranged tightly. You’ll notice the chipset covered with thermal paste.

Most antennas do not use latches and pads.

Xperia Z1 Compact Disassembly_7

The handset uses two microphones to help with noise reduction. You can also see the main speaker here, the rear of the speaker is covered to protect it from water.

  • Mac

    Why didn’t I think of that..
    Imma try there, but I just wish it worked with Easy rooting toolkit. I know ppl are going 2 get pissed and all when they realize that they can’t put apps on their new 64gb sdxc. Why the h*ll is it not working without root when both my acro s and even the neo had no problem at all..
    Kitkat maybe fix it, or at least I hope so! Damn.. -_-

    So is it plastic?!?!

  • HeyYo.

    Does this mean that Sony could just as well made the battery replaceable or does that lose the IP rating? ZR was IP rated with a removable backcover though…

  • g0r007

    Someone know where to buy a original back cover with the sticker adhesive ? I scratched mine… and yes, the back is plastique

  • Heavyhms

    How is granted the impermeability of the earpiece and notification led?
    On my Z1Compact the tiny membrane visible over led seems to be connected only on two sides, leaving the upper side merely close up to the plastic frame. From a close observations is possible to see a space small enought to insert a slim piece of 3M Scotch (i’ve noticed the first time during the first led blink).
    I suppose the led underneath and the earpiece are water shielded otherwise: because i have already tested twice (for a total of 10 min.) on a water recipient whitout visible infiltrations or failure.
    On the teardown photo this area is not clarely visible.

    Very interesting thing I just come across at – I could choose any number of items (from the list) at very heavy discount rates (up to 75% off online) – more we buy more discount – I never seen this before.

    The tech in the video should know that paper can cause static electricity and should not be within 12 inches of any PCB. Definitely shouldn’t be setting them on the paper. Try getting some ESD training.
